By the laws of the State of Maryland, every free colored person was required to have what were called "free papers," which must be renewed frequently, and, of course, a fee was always charged for renewal. They contained a full and minute description of the holder, for the purpose of identification. This device, in some measure, defeated itself, since more than one man could be found to answer the general description; hence many slaves could get away by impersonating the real owners of these passes, which were returned by mail after the borrowers had made good their escape. To use these papers in this manner was hazardous both for the fugitives and for the lenders. Not every freeman was willing to put in jeopardy his own liberty that another might be free. It was, however, often done, and the confidence that it necessitated was seldom betrayed. Douglass had not many friends among the free colored people in Baltimore who resembled him sufficiently to make it safe for him to use their papers. Fortunately, however, he had one who owned a "sailor's protection," a document describing the holder and certifying to the fact that he was a "free American sailor." This "protection" did not describe its bearer very accurately. But it called for a man very much darker than himself, and a close examination would have betrayed him at the start. In the face of all these conditions young Douglass Was relying upon something besides a dubious written passport. This something was his desperate courage. He had learned to act the part of a freeman so well that no one suspected him of being a slave. He had early acquired the habit of studying human nature. As he grew to understand men, he no longer dreaded them. No one knew better than he the kind of human nature that he had to deal with in this perilous undertaking. He knew the speech, manner, and behavior that would excite suspicion; hence he avoided asking for a ticket at the railway station, because this would subject him to examination. He so managed that just as the train started he jumped on, his bag being thrown after him by some one in waiting. He knew that scrutiny of him in a crowded car en route would be less exacting than at the station. He had borrowed a sailor's shirt, tarpaulin, cap, and black cravat, tied in true sailor fashion, and he acted the part of an "old salt" so perfectly that he excited no suspicion. When the conductor came to collect his fare and inspected his "free papers," Douglass, in the most natural manner, said that he had none, but promptly showed his "sailor's protection," which the railway official merely glanced at and passed on without further question. Twice on the trip he thought he was detected. Once when his car stood opposite a south-bound train, Douglass observed a well-known citizen of Baltimore, who knew him well, sitting where he could see him distinctly. At another time, while still in Maryland, he was noticed by a man who had
